I am very interested in using Avaire in my bathroom but I have 2 concerns about it. The first is does the grout shrink and or crack over a period of time? When I say shrink I mean does the grout pull away from the tiles creating a open seam that water and dirt can enter.
My second concern is seeing this is a floating floor and you leave a 1/4 in gap between the walls, except next to the bathtub where you seal it with caulking, can you prevent water from getting to the subfloor? Example is if the toilet overflows.
